Book excerpt: Developing countries may not have full-fledged welfare states like those we find in Europe, but certainly they have welfare state systems. For comparative social policy research the term "welfare state systems" has many advantages, as there are numerous different types/models of welfare state systems around the world. This path-breaking book, edited by Christian Aspalter, brings together leading experts to discuss social policy in 25 countries/regions around the world. From the most advanced welfare state systems in Scandinavia and Western Central Europe to the developing powers of Brazil, China, India, Russia, Mexico and Indonesia, each country-specific chapter provides a historical overview, discusses major characteristics of the welfare state system, analyzes country-specific problems, as well as critical current and future trends for further discussions, while also providing one additional major focal point/issue for greater in-depth analysis. This book breaks new ground in ideal-typical welfare regime theory, identifying now in total 10 worlds of welfare capitalism. It provides broad perspectives on critical challenges which welfare state systems in the developing and developed world alike must address now and in the future. It will be of great interest to all scholars and students of social policy, social development, development and health economists, public policy, health policy, sociology, social work and social policy makers and administrators. This book is a reference book for researchers and social policy administrators; it can also serve as a textbook for courses on comparative social policy, international social policy and international social development.
